Abstract: Changes in the contents of betaine, soluble sugars, free amino acids and organic acids in the leaves of the young grapevine plants (Vitis vinifera L.) during water stress were investigated. The results showed that the contents of both soluble sugars and free amino acids increased in the grape leaves under water stress, moreover, that they continuously increased as water stress was developing. Compared with drought-sensitive Red Globe grapevine, the contents of both soluble sugars and free amino acids in the leaves of drought-resistant Long Yan grapevine increased to a greater extent. Under moderate water stress, the contents of inositol, fructose, and glucose + sorbitol + mannitol increased in the leaves of Long Yan grapevine plants, especially, the inositol content enhanced almost 1.5-fold. Throughout water stress, the content of both betaine and organic acids were rather low.

Key words: Grapevine, Water stress, Osmoprotectants
